Fantasy Tip: Breida will be the primary backup to McKinnon, but Joe Williams, Jeremy McNichols and Raheem Mostert are also in the mix and fighting for touches, too. Breida will be a good late-round handcuff to McKinnon, particularly in PPR formats.

Fantasy Tip: McKinnon is perhaps free agency's biggest winner in terms of fantasy value. In each of Shanahan’s two seasons as Falcons offensive coordinator, Freeman accounted for more than 1,500 yards from scrimmage. Matt Breida is tentatively expected to fill the Tevin Coleman role. McKinnon should be treated as a RB2 with RB1 upside in 2018, while Breida should be considered a high-upside flex option.

San Francisco 49ers head coach Kyle Shanahan said "there's so many things" he likes about RB Jerick McKinnon, adding that he got "lost" while immersing himself in watching his game film. "This guy is violent, doesn't turn anything down," Shanahan said. "What is a huge bonus on him is when you talk about the pass game. When it comes to separating and beating linebackers and safeties in man-to-man coverage, I definitely think he's an issue for teams."

Fantasy Tip: Shanahan is sold on McKinnon, which bodes well for his fantasy outlook in 2018. Fantasy circles have long envisioned a breakout from the former Vikings tailback, and while that hasn't exactly materialized yet, it could be this change of scenery for it to finally come to fruition. With Carlos Hyde gone, McKinnon might be in position to claim the starting gig, though Matt Breida impressed last year and also figures to see a lot of work.

He has a $6.9 million option bonus for the 2021 league year to be exercised prior to the end of the 2020 league year.

Fantasy Tip: McKinnon has developed solid hands out of the backfield and is a threat to run and catch. He'll be a solid RB2 in PPR fantasy formats in the upcoming season, as you can expect the 49ers to lean upon their new toy quite heavily.

Fantasy Tip: McKinnon turned into a decent receiver in the backfield. He put together a 150-570-3 line on the ground and a 51-421-2 line through the air last season. He'll have some RB2 viability in PPR.
